وَإِنْ تَرَكَ رَمْيَ جَمْرَةِ الْعَقَبَةِ فِي يَوْمِ النَّحْرِ: فَعَلَيْهِ دَمٌ.
Translation: Whoever omits stoning Jamarat al-Aqabah on the Day of Sacrifice owes dam.
Yawm al-nahr is the tenth of Dhu al-Hijjah, when the stoning rite concerns Jamarat al-Aqabah. Missing that day’s prescribed stoning incurs dam.
This differs from missing one out of three stations on the subsequent days, where the text stipulates charity.
